Cellular Energetics: The Rate of Cellular Respiration and Photosynthesis over Time Among Various Variables By: Ethan Barnett Introduction Cellular Energetics is the broad term that encompasses both cellular respiration and photosynthesis and refers to how energy changes and reacts within cells. Cellular respiration is the process by which cells break down sugars (ATP) in order to produce energy for other chemical reactions. Cellular respiration takes place mainly in the mitochondria and the reactants

Understanding the function of cellular respiration and fermentation is easy to learn. However it is more difficult to learn the process of glucose being converted into energy. Cellular respiration has four stages‚ of which a phase can consist of eight or ten steps. In the Krebs Cycle alone‚ there are ten steps‚ where the input of Acetyl CoA is eventually reconverted back into oxaloacetate. Fermentation is also no different. It can be difficult for students to understand what the role of NADH

Problem: Does prior exercise affect the ability to squeeze a clothespin? Hypothesis: After exercise‚ people will be able to squeeze the clothespin faster than those without prior exercise. Materials: For this experiment a timer and a clothespin were used. Methods: To begin this experiment an individual was asked to squeeze a clothespin as many times as possible within one minute and the results were recorded. Then this same individual was asked to exercise (run in place‚ preferably)

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

Lab 5Cellular Respiration Introduction: Cellular respiration is an ATP-producing catabolic process in which the ultimate electron acceptor is an inorganic molecule‚ such as oxygen. It is the release of energy from organic compounds by metabolic chemical oxidation in the mitochondria within each cell. Carbohydrates‚ proteins‚ and fats can all be metabolized as fuel‚ but cellular respiration is most often described as the oxidation of glucose‚ as follows: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 kilocalories

Part 1. Cellular Respiration Prarthana Minasandram Partner: Ben Liu Introduction Purpose: To examine the rate of alcoholic fermentation using various carbohydrates. Hypothesis: If the yeast is placed in 5% glucose or sucrose solutions‚ then carbon dioxide production will increase over time. If boiled yeast is placed in a 5% sucrose solution‚ then carbon dioxide production will remain constant. Variables Independent variable: Carbohydrate solutions (5% solutions of glucose and sucrose) and

Cellular Respiration In this lab the effects of different substrates on the rate of cellular respiration is being put to a test which is a very interesting experiment. The three major substrate solutions being used for this experiment are glucose‚ maltose‚ and alanine. The issues this experiment addresses are cellular respiration occur in different stages which are glycolysis‚ citric acid cycle‚ and fermentation. In this lab the experiment determines the effect of different substrates on

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. 1. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts? They are most
